    You can request relief if you experienced extraordinary circumstances like natural disasters, serious illness, death in the family, or other unavoidable events. You may also qualify if CRA processing delays or errors caused penalties or interest to accumulate, or if paying these amounts would create severe financial hardship.

  • What documents do I need to attach to the form?

    Attach supporting documents such as medical records if health issues prevented timely payment, employment termination letters if job loss was a factor, financial statements proving your inability to pay, and correspondence with the CRA that demonstrates any delays or errors on their part.

  • How do I submit my application?

    You can submit your completed form and supporting documents to the CRA by fax (if applicable) or electronically through your CRA My Account or My Business Account.

  • What happens after I submit my application?

    The CRA will review your application and may approve your request partially or entirely, which could reduce or eliminate interest charges. If your application is denied, they will provide reasons and guidance on further actions. They may also request additional information, which could delay the decision until you respond.

  • How long does it take for the CRA to process my application?

    Processing times can vary significantly, often taking 8 to 12 months. During this time, it's important to continue making minimum payments to avoid further accumulation of interest.
